reprojecting an extent

RhysDonoghue — Thu, 28 Apr 2011 03:58:22 GMT

I copied the project and extent sample code from here:

http://resources.esri.com/help/9.3/arcgisserver/apis/Flex/samples/index.html?sample=ProjectPoint

but get this error:

"1119: Access of possibly undefined property graphics through a reference with static type com.esri.ags.event:GeometryServiceEvent"

Anyone know why? I suspect it is because one of the namespaces has been deprecated in the example.

Are you using the 2.x or 1.x API?

If you're using the 2.x API, the matching 2.x sample is at

Champion Bjorn, I should have seen this. It's working now thanks.

Hi Bjorn

I got the sample working ok but having a couple of issues. We want to use basemaps with different projections (not at the same time), i.e. WKID 102100 and WKID 2193. I was hoping that when the user changes basemaps, I can get the current basemap extent, re-project it into the new projection and bring up the new basemap in the same location. This is not working. I suspect that when leaving 102100's projection and changing to 2193's projection, the map still thinks it is in 102100. How can I get around this? Do I have to add and remove the basemaps via Actionscript?
